DAC Worldwide's PID Controller Trainer, Level Control (608-000) is a realistic, rack-mounted process control simulation application allowing for basic training in industrial process control using a simulated level process application in conjunction with an optional PID process controller or PLC with analog capabilities. The system includes a power supply and connections for an external chart recorder and a signal generator.

The system allows for classroom training of operators and maintenance technicians in the use of controllers in both automatic and manual modes. Indicators allow students to see the effect that a change in controller output has on final control element position and the process variable being controlled.

Based on the capabilities of the optional controller, the system allows the controller to be tuned to provide proportional, proportional plus integral (reset), proportional plus derivative (rate), and proportional plus integral plus derivative control actions. Both open and closed loop tuning techniques can be used.

Control valve response time and process tank capacity can be adjusted. The PID Controller Trainer, Level Control accepts and provides external 4-20mA DC control signals, allowing it to be interfaced with a variety of optional or user-supplied controllers. Optional signal generators and strip chart recorders can be easily connected.
